Title: Optical information recording/reproducing device
Inventor: SHIKICHI SATOSHI
IPC: G11B7/09
Filed: 1989-02-01
Abstract: PURPOSE:To move an optical system to its reference position by storing this reference position within a movable range in case the supporting position of the optical system is shifted from its reference position in the movable range. CONSTITUTION:An optical system 110 is prepared to form an optical spot on a track of a recording medium 101 together with a drive means for the system 110, a support means for the system 110, and a system controller 119 which stores the reference position of the system 110 within a movable range. Thus the system 110 is always supported at its reference position within a movable range despite the shift of the supporting position of the system 110, i.e., in case the system 110 is shifted from its supporting position owing to the empty weight of the system 101. Thus it is possible to always perform a tracking servo lead-in action for an objective lens 110 of the optical system at the reference position within a movable range in a tracking servo lead-in state.

Title: Method and device for reproducing magnetic signal
Inventor: HAMAMOTO MASAKI
IPC: G11B5/02
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for reproducing magnetic signals which suppress the signals from the no-heating up region of a magnetic recording medium from being mixed in reproduced signals, that is caused by the medium temperature being deviated from a magnetic compensation temperature in the no-heating up region of the magnetic recording medium. SOLUTION: First, reproduced signals during heating up are obtained by reading magnetic information in a reproducing region in a heating up state. Second, the reproduced signals during no-heating up are obtained by reading the magnetic information in an approximately same region with a reproducing region in a no-heating up state. By subtracting the reproduced signals during heating up from the reproduced signals during no-heating up, the reproduced signals during heating up are compensated for and the signals are made into information reproduced signals representing the recorded information in the reproducing region.

Title: Manufacture of glass fusion airtight terminal
Inventor: AIHARA YOSHIKI
IPC: H01J9/32
Filed: 1981-02-16
Abstract: PURPOSE:To facilitate removal of bubbles, which develop within glass during the fusion of the glass and have diameters over a given value, and facilitate equalized fusion of the glass by carrying out the process of glass fusion, which is comprised in the manufacture processes of a airtight terminal, in a specified vacuum. CONSTITUTION:After a metal terminal 102 is set to a tool so that the terminal 102 is located within the holes of a metal base plate 101 and a glass tablet 301, the heating and fusing process of glass is carried out in a vacuum of below 10<-1>mm.Hg pressure. A large bubble (B) is developed in the glass during the heat fusion, and floats on the surface of the glass before it is eliminated (C). Thus, large bubbles B with a diameter of above 10<-1>mm. is easily removed from the glass due to the difference between the pressures of the bubble B and the vacuum. As a result, equalized glass fusion can be easily carried out without causing any bubble or hole within or on the surface of the glass after the fusion.

Title: Magnetoelectric transducer
Inventor: NARIMATSU AKIYOSHI
IPC: G01R33/09
Filed: 1980-02-22
Abstract: PURPOSE:To monotonously vary the detection output characteristics of a magnetoelectric transducer over a wide range by employing a signalling magnetic field generator provided with a magnetic air gap and a magnetic sensor of given constitution. CONSTITUTION:Stable magnetoelectric conversion, independent of temperature and hysteresis, is performed by a magnetic sensor MS1 consisting of a ferromgnetic magnetic resistance element MR1 provided with current biasing current path portions IC1 and IC2 each inclined at 45 deg. with respect to the edge portion (e) and a biasing magnetic field generator MGB1 which applies a bias magnetic field in the 45 deg. direction with respect to the bias current. On the other hand, a signalling magnetic field generator MGS is formed by magnets Mg1 and Mg2 which interpose a magnetic air gap UG and generate magnetic fields in different directions from each other. Relatively displacing the sensor MS1 and the magnetic field generator MGS in the direction of crossing the air gap UG causes the corresponding detected magnetoelectric conversion value to monotonously vary over a wide range in the positive direction or the like. Accordingly, an optimum magnetoelectric transducer is obtained for an analog servo or displacement transducer.

Title: Device of car for running at constant speed
Inventor: KAJIWARA YASUNARI
IPC: G05D13/62
Filed: 1982-02-10
Abstract: PURPOSE:To ensure the safety and to reduce the burden of the operator, by detecting obstacles in front of a car, a distance and a relative speed with a preceding car, computing the optimum car distance and the optimum car speed, controlling the speed and outputting alarm at failure. CONSTITUTION:In setting a constant speed button, the distance and the relative speed with the preceding car or the obstacle are computed at a CPU6 with a car speed sensor 1 and an optical range finder 5 and the substantial distance between cars is calculated. The substantial distance between cars is the subtraction of the relative speed multiplied with an experimental coefficient from the actual car distance. The CPU6 accelerates or decelerates an actuator 3 to keep a desired distance for the substantial distance between cars in response to the car speed. When the preceding car speed is slower than the set car speed, the CPU6 decelerates an actuator 3 to keep the distance suitable and when the preceding car is faster, the car runs at the set constant speed. When the processing is not effected by only the acceleration or deceleration due to a car intruded, an alarm 7 is effected to alarm with an alarm device 8. Thus, the burden of the driver is reduced.

Title: Method of recording and/or reproducing video signal, apparatus for the method and magnetic recording carrier obtained by the method
Inventor: HERARUDO DE HAAN
IPC: G11B15/14
Filed: 1987-02-03
Abstract: When, for example, MAC signals (inter alia C-MAC or D2-MAC signals) are recorded directly on a video recorder and no special steps are taken, information will be lost as a result of the change-over from recording by means of one write head (7) to recording by means of another write head (8). The relevant signals to be recorded comprise a sequence of lines with a first signal block (Fi) containing a line-synchronising signal and at least one additional signal, and a second signal block (Si) containing the chrominance and luminance information of the video signal. In accordance with the inventive step specific first signal blocks (F1, Fi, Fj, Fk) or at least the additional signals of these first signal blocks are accommodated in a second signal block (Sn) of a non-relevant video line and are subsequently recorded on the record carrier. After the relevant second signal block (Sn) has been read from the record carrier the relevant first signal blocks, or at least the additional signals of these first signal blocks, are extracted from the second signal block and re-inserted into the data stream of first signal blocks at their original locations. The relevant first signal blocks may be those first signal blocks during which the heads are switched (Fig. 1a and 1b) or may be other (subsequent, when viewed in the time) first signal blocks (Fn-3 to Fn) which can no longer be inserted into the data stream of the first signal blocks because these first signal blocks, during which head switching is effected, have been repeated earlier in the data stream (Figs. 7a and 7b).

Title: Dew condensation detecting method for filter paper type gas purifying filter
Inventor: HASHIMOTO MASAHIRO
IPC: B01D46/42
Filed: 1987-02-02
Abstract: PURPOSE:To perform speedy and accurate detection without any decrease in performance by measuring a variation in the conductivity of a predetermined part of a filter material which constitutes a filter. CONSTITUTION:Lead wires 2 are connected to separators 12 and 12 at both ends and a constant voltage V is applied to the filter material 1 through those lead wires 2; and a resistance R with a constant value is connected in parallel to the filter paper 11 and a variation in the conductivity of the filter material 11 is measured from variation in the voltage (v) across the resistance R to detect dew condensation on the filter 1. Namely, if dew condensation is caused, the filter material 11 decreases in electric resistance and a current flows to the filter 1, so that the voltage (v) across the resistance R drops abruptly. For the purpose, the voltage (v) is compared with a predetermined reference value to decide that the dew condensation occurs when the voltage (v) is smaller than the reference value or that the dew condensation is not caused when the voltage (v) is larger than the reference value. Thus, whether or not the dew condensation occurs is detected accurately and speedily according to the predetermined reference value.
